A recent eBay find, this beautiful example by Carl Goldberg, Haida, ca. 1900, combines techniques - the mottled surface colors, reddish hue, and iridescence appears similar to the iridescent metal-oxide reduction technique employed by enamelist Maximilian Boudnik for Joseph Knizek at Antonienhutte (at about the same time), and the beautiful wheel cut lines in a spreading pattern. Note the closeup of the cuts - the perfectly smooth surface is an indication of age and the use of iron or steel wheels. Newer cut glass will show striations on the surface consistent with the use of diamond surfaced wheels. The shape of this vessel is documented in Das Bohmische Glas, 1700-1950, Band IV, plate IV.457 in a different finish with Goldberg's signature silver deposit technique. It seems to me that Goldberg had a fascination with refining techniques, and examples of just about every discipline can be found. According to the indispensable reference book Collectible Bohemian Glass, 1880-1940, by Robert and Deborah Truitt, Goldberg was supportive of the glass school in Novy Bor, and executed many of its designs.
